number. The portable has one directory number and the wired
telephone has another directory number.
The portable and the wired telephone are not twinned. An incoming
call only rings on the telephone whose directory number was dialed.
Calls can be active on both telephones. For example, when a call is
active on the portable, a second call can be made on the wired
telephone. (To add a mobility feature to the wired telephone, forward
calls from the wired telephone to the portable when you will be away
from your desk.)
Telephones that are assigned in parallel on the COMPANION 200
system are supported by separate lines to the host switch. The
portable is supported by an access line connecting the Controller to
the host switch. The access line is programmed at the host switch as
though it supports a single standard analog telephone. The wired
telephone is wired directly to the host switch.
• Parallel assignment can be used with any host switch.
• The wired telephone can be a featured, digital telephone or an
analog telephone.
• The portable and the wired telephone can be provided with
different sets of host switch features. The portable is limited to
the host switch features available to a standard analog telephone.
Changing the feature settings of an access line will only impact
the portable supported by that external line (the feature settings of
the wired telephone will not change).
• A call in progress on the portable can be continued on the wired
telephone by using Call Transfer or any other similar host switch
feature. The call is interrupted briefly while the feature is
performed. Similarly, a call in progress on the wired telephone
can be continued on the portable by using an applicable host
switch feature.
• Privacy of telephone conversations is ensured when parallel
assignment of host switch directory numbers is used. Since the
directory numbers are not shared, access to a conversation in
progress on one telephone cannot be gained through the other
telephone.
Single Call Arrangement of Multiple Appearance Directory Number
(MADN SCA) is a host switch feature that allows the assignment of
the same host switch directory number to any number of lines that
